Default Second yoyo-BOINC factor

yoyo@home user blitzen found a P44 from the Aurifeuillian-M of 24158+1. The Math FAQ pages explain Aurifeuillian factors; this one is 22079+21040+1. This is the second known factor of this primitive; a P21 was previously found by ElevenSmooth. The composite cofactor is reduced from C305 to C262.
